Today at 17:06 UTC there was an magnitude 3.7 earthquake (automatic magnitude) not far from Madrid, Spain. I am not sure if this earthquake was felt in Madrid or nearby towns. But so far nothing has been reported so far on EMSC web page.

It is unlikely that aftershocks are going to happen in this area. As this was inner-plate earthquake that took place here. They happen every few years in Spain and other places in Europe that normally do not have any earthquake activity.
